I have a 2017 Yukon XL Denali. My hitch has the same part number as yours has. My max tow for the truck is 7,900 because of the XL and 4x4. I would have thought that the longer wheelbase, larger engine and transmission would up the rating. Apparently the brakes and the suspension is the limiting factor. I do like the 1,000# tongue rating, sometimes RVs can get nose heavy and roads get bumpy. I am glad I took the cover off to see the hitch. There has never been a receiver in the hitch. There will be one in there tomorrow.
